Choong et al.Problem statement: Steel making slag from Electric Arc Furnace (EAF) is an abundant by-product in Malaysia steel making industry. It has potential to be used for heavy metal removal from contaminated water or waste water. Approach: The aim of this study was to investigate the characteristic and behavior of manganese removal by using EAF slag for efficient metal removal. The … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 8,104 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExponential-Hyperbolic Model for Actual Operating Conditions of Three Phase Arc FurnacesMahdi Banejad, Rahmat-Allah Hooshmand, Mahdi Torabian EsfahaniProblem statement: The Electric Arc Furnace (EAF) is a non-linear load and creates power quality related problem. Therefore, accurate modeling of the EAF is essential. Approach: In this study, an optimal model for EAF in time domain called exponential-hyperbolic, was proposed to describe the behavior of the EAF for all of the operating conditions and it does not need the … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,247 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDynamic Modelling of an Industrial Smelter Furnace and Converter Off-gas SystemHelen Shang, Megan Dillabough, Phillip Nelson, Bryan SaltIn smelters, metal ores or concentrates are smelted to reduce a metal oxide to a metal through a series of reactions and processes. In a smelting process, a large amount of off-gas emissions are often generated, which can cause serious environmental and plant hygiene problems if not properly treated. Off-gas systems extract and treat the off-gas emissions, and ensure that … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 7,153 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptimization of an Automatic Blast Furnace through Integrated Simulation ModelingAli Azadeh, S. F. GhaderiThe objective of this study was to develop an integrated simulation model of an automatic blast furnace in a full-scale steelmaking factory. The integrated simulation model introduces a set of optimizing alternatives through sensitivity analysis. The simulation model is built by considering all major and detailed operations and interacting systems of the blast furnace workshop. The workshop is composed two … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 7,092 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleWaste Heat Recovery by Heat Pipe Air-Preheater to Energy Thrift from the Furnace in a Hot Forging ProcessLerchai Yodrak, Sampan Rittidech, Nattapol Poomsa-ad, Pattanapol MeenaProblem statement: Currently, the heat pipe air-preheater has become importance equipment for energy recovery from industrial waste heat because of its low investment cost and high thermal conductivity. Approach: This purpose of the study was to design, construct and test the waste heat recovery by heat pipe air-preheater from the furnace in a hot brass forging process. The mathematical model … …American Journal of Applied Sciences, Vol. 7, Issue 5 · 31 May 2010 · 8,209 accessesView PDFCite
